        The importance of managing the exposure to radiation for radiological technologist is becoming more conspicuous as modern medical care increases the number of hospital exams involving radiation and as work of radiological technologists expand and increase in areas using advanced medical equipment for diagnosis and treatment purposes involving radiation. Measurements for individual exposure dose to radiation can differ according to the equipment and facilities in the work environment and the average number of exposures an individual is involved in. Therefore, systematic and reasonable controls on the exposure dose to radiation can be attained from core data. Shallow dose/Deep dose measurements were taken according to the year of the measurement, the technologist’s occupation post, gender, department, and age over a five year period from January 1, 2003 to December 31, 2007 using a sample of radiological technologists from ten general hospitals throughout S. Korea. When comparing individual exposure dose of each radiological technologist, there was no significant difference in the mean exposure dose according to the year the measurement was taken (p>0.05). Mean exposure dose for Deep/Shallow according to gender showed that men received significantly higher exposure dose than women (p<0.001). Mean exposure dose for Deep/Shallow according to age showed an increase in exposure dose as age decreases, however, it was not statistically significant (p>0.05). According to occupation post, technologists working in nuclear medicine received significantly higher dose than other occupation posts (p<0.001). The results of individual exposure dose were under the dose limits in accordance to all nuclear regulations. Furthermore, since stochastic effects may occur with long-term exposure to low level radiation, individual exposure dose data was thoroughly managed and the principle of As Low as Reasonably Achievable (ALARA) was implemented when establishing the design of this study.
